How to Setup Data File Containing Questions with Rotations or Randomization

Introduction

Rotations and randomizations that occur between respondents within a question need to be removed from the data prior to creating the data file. This article describes data set setup for questions with rotations or randomizations.

Requirements

Survey which randomizes or rotates the order for questions.

Method

For example, if the questionnaire said:

Q1	Which of these have you eaten in the past week? RANDOMIZE ORDER OF 1 AND 2

	McDonald’s
	Taco Bell
	None of these

Then half the sample will have been asked:

Q1	Which of these have you eaten in the past week?
	McDonald’s
	Taco Bell
	None of these

And the other half will have been asked:

Q1	Which of these have you eaten in the past week?
	Taco Bell
	McDonald’s
	None of these

When the data is exported, it should be done using the order in the questionnaire. That is, even though Taco Bell was shown first half the time and second half the time, the data file should be created as if Taco Bell was always shown second.
